VCU: common questions
What microcontroller does the VCU use?
The VCU is built around the STM32H743ZITx, from the STM32 family.
How big is the VCU PCB?
The VCU measures 100 × 100 mm, has 4 copper layers and is 1.6062 mm thick.
How many components are on the VCU?
304 components, from 94 distinct parts. The full bill of materials is listed on this page.
Where can I download the VCU design files?
From the NTURacingTeam/nturt_kicad repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the VCU design in my own project?
The repository has no license, so all rights stay with NTURacingTeam. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the VCU without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
